no 5 years are nothing for an animal that can get more than 150 years old...And please...Thailand...thats not even a functional country.
explain me please, why an anadromous fish that lives in salt and freshwater was nable to inhabit tropic waters in more han 350 million years. What do you think is the reason for that?
it didnt have enough selective pressure for it to move and adapt to tropical waters.
